Cobá

People settled between the lagoons of Cobá around two thousand years ago, and by the Late Classic period, from roughly 600 to 900 CE, the place had become a major power in the northern lowlands. It spread across some 80 square kilometres and may have held around 50,000 people.

Cobá's strength lay in trade and in its reach across the peninsula. After about 900 CE its influence faded as Chichén Itzá rose to the north. Building continued into the 1200s and 1400s, but the city stood largely abandoned by the time the Spanish reached the coast.

The Maya called them sacbeob, the white roads. At Cobá at least 45 have been mapped, raised causeways of packed limestone rubble faced in white plaster, running dead straight through the forest. Some link the site's own groups; others reach distant towns.

The longest, known as Sacbe 1, runs more than 100 kilometres west to Yaxuná, near Chichén Itzá, and is the longest known Maya causeway. Nothing so extensive survives at any other site, which made Cobá the hub of the largest road network in the ancient Maya world.

The ruins spread across several groups set among the trees and lagoons. The Cobá Group holds a pyramid and ball courts near the entrance; the Macanxoc Group, deeper in, is a cluster of stelae and altars; the Painted Group keeps traces of colour on its lintels.

At the far end stands Nohoch Mul, the great mound, a 42-metre pyramid that is the tallest on the northern Yucatán Peninsula and higher than El Castillo at Chichén Itzá. A steep flight of roughly 120 stone steps climbs to a small temple at the summit.

Cobá's rulers set down their reigns on tall stone stelae, several of them clustered in the Macanxoc Group. The carvings are badly weathered now and sheltered under palm-thatch roofs, but they still preserve dates and dynastic history from the city's peak.

In 2020, researchers reading these monuments identified fourteen rulers of Cobá, at least one of them a woman thought to have governed in the city's early centuries. Direct evidence of a queen is rare in the Maya record, which makes Cobá's stelae unusual.

Cobá is spread out and quiet, more forest than plaza. The paths between groups run long enough that many visitors rent a bicycle or hire a pedal-taxi at the gate. Birds and howler monkeys are often louder than the crowds.

For years the climb up Nohoch Mul defined a visit, until INAH closed it in 2020 to protect the worn steps from heavy foot traffic. In December 2025 it reopened, with a wooden staircase laid over the ancient stone and access managed in small timed groups. Whether you climb or not, the barriers around the stelae and the marked paths keep the site standing.
